If 10 `cm^(3)` solution of `H_(2)O_(2)` on decomposition gives 150 `cm^(3)` of `O_(2)` at STP, then volume strength of `H_(2)O_(2)` is

A

15

B

30

C

20

D

10

Text Solution

Verified by Experts

The correct Answer is:
A
`2H_(2)O_(2) rarr 2H_(2) O + O_(2)`
`10 cm^(3) H_(2) O_(2) rarr 150 cm^(3) O_(2) implies 1 cm^(3) H_(2) O_(2) rarr 15 cm^(3) O_(2)`
Hence the volume strength of `H_(2) O_(2) ` is 15
